Hello,

Try the following javascript.
JS:

<script type="text/javascript">

    function OnClientClick()

     {

        var list = $find("<%=RadListBox1.ClientID %>");

        for (i = 0; i < list.get_items().get_count(); i++)

        {

          alert(list.getItem(i).get_value());

        }

    }

    </script>

Thanks,
Princy.
